British and Irish Lions

The 31-year-old, who can play either lock or in the back row, has been an ever-present in the league this season.

Head coach Richard Hill said: "It is fantastic news that Roy has signed a new two-year contract with us. He is an incredibly hard-working member of the pack and a great team player who is constantly trying to raise his game.

"This signing shows Bristol's determination to remain a successful and improving Guinness Premiership outfit and Roy will play a significant part in our plans for the future."

The 6ft 4ins, 17st 8lbs Winters joined Bristol for Harlequins in May 2005.

Assistant coach Graham Rowntree says The British & Irish Lions will have to be fully focussed to avoid a potential banana skin when they face The Barbarians a week today.

Three former British & Irish Lions will line-up against an England XV at Twickenham Stadium on Sunday as the Barbarians warm-up for their showdown with the 2013 tourists in Hong Kong next week.

Radike Samo, one of only two players still playing top level rugby in Australia who placed against the 2001 British & Irish Lions, will return to top flight action with Queensland Reds against the Stormers in Cape Town on Sunday.
